Location number: Well numbers give the location of wells according to General Land Office surveys and according to the following formula: Township--Range--Section, 160-acre tract within that section, and the 40-acre tract within the quarter section.

The 160-acre and 40 acre tracts are designated a, b, c, or d in a counterclockwise direction beginning in the northeast quarter. For example: well 18-6-1cd is located in the SE SW sec. 1, T. 18 S., R. 6 E.
